'Application filed. June 10, 1926. Serial No. 115,077.1`Y l yThis invention relates to improvements in I secure a Tfhead 11 which is horizontally cultivators vand more particularly to an imdisposed and extends transversely kot the provement in the method of mounting the vehicle. At the approximate center of this cultivator teeth or sharesvso that they may T-head, I mount a lever 12swinging in a be' very readily adjusted toward and away plane extending longitudinally of the vehiclel 55 from one another. v f Y Y upon a pvot 13 spacedabove the upper sur- An important objectoi' the invention is face of the head andinounted infa vbracket `to produce a device of this character which 14C, the upper end of 4which is extended above 'eliminates thevnecessity for nuts, bolts, and the pivot and formed asa segmentl toreo- 1Orthe like; 4 yaction with a latch l16 mounted-uponfand- 60 A still further .object of the invention is controllable from the upper end ot thelever. to provide a device ot this character so con- The bracket 14 below the pivot 13' is .pro- V vstructed that the collectionof dust and dirt vided with an opening` 17 across whichv *thek 4' in the working partsis eliminated and the lower end of the lever operatesv and this l5 life of the mounting thus extended. l lower end of the lever is forked,` as at 18. 65Y

Y A further object ot the invention is to At the inner side of the head, I form a provide la'devi ce of this character which may" plurality ot vertical openings 19 spacedlonbe very readily and cheaply produced and gitudinally of the'head and each constructed which may be easily applied to cultivators to permit-the passage of the helve v2O of: al 20 as at present constructed.v ground working implement' or share 21. *70* Affurther obfect of the invention is to The helveof this ground working` implement provide a'device of this character whereby is preferably in the form of a flat bar and the set of the cultivator teeth or shares mayv is surrounded by lower and -upper collars` be readily adjusted to permit use ot the cul- 24 and 25 secured in position by set-screws "25 tivator in lmiddles of different widthsv or 23. .Thel collar 25 which ab-utsthe upper75 plant rows, in the working of which'the ciilsurface of the head llhas formed thereonv tivator implements must be' differently an arm 26 which projects through the-open- V spaced. i y Y. ing 1'? and .engages in the notch 18 of the le- These and other objects I attain by the ver 12. i

The rear end of this link khas an eye 38 through which* the end ofthe arm Stis directed.

' It will bevobvious that since the arms 26 and 34 extend in opposite directions and are 1 jconnected With'the lever at opposite sides'of the pivot thereof, a movement 'of the lever will result in corresponding movements of the helves 2() and 80. in the samedirection, thereby swinging. VWith these helves the ground vWorking implements 2l connected thereto 'to move them toward or away from the center of the-cultivator. It Will also be jobviou's'that this adjustment can be made at eitherside of the cultivatorto accommodate a sudden Widening or displacement of ytheplants of a .row Without the necessity of the @operator stopping the lcultivator or Y releasing more than oneV of the handles 39 thereofl While the structure hereinbefore set orthhas been illustrated With-the par- Y f ticular type ofcultiva-tor, it is obviously capable of use with cultivators of other types.

- Since certain ychanges are possible in the construction and arrangement of the variousparts hereinbefore illustrated, I do not flimit myself to such specific structure eX- ported from the head at opposite sides of lthe leveran arm rigidly secured to each cept as hereinafter claimed.l
